DeepCool Quanta DQ1250 1250W PSU Unboxing & Overview
All and all, we are fairly pleased with the DeepCool DQ1250. It seems to deliver on all of its promises, and offers fairly solid build quality. It passed JohnnyGuru’s rigorous testing with flying colors, and received great marks.That being said, there are things we think DeepCool could have done better. Firstly, the hardwired cables could definitely stand to be a bit longer, and while they’re at it, they should also match the included modular cables. We would have loved to see all black ribbon-type cables, or at the very least all black cables in general, as serious builders will not like like the color-clashing “rainbow spaghetti” that is the 20+4-pin connector.

It's certainly not the best high-wattage PSU in the market but it offers near excellent performance with relatively low noise levels and at a tempting price tag so what's more to ask? On top of that add the 5 years warranty offered by DeepCool and you've got yourself a PSU that should appeal to a large segment of the market and that's why it gets our Platinum Award.

Most of performance aspects were excellent. Yes, I've seen better regulation from the likes of Seasonic and Super Flower, but this unit is no slouch. At 1.3% averaged stability in the hot box, this unit did extremely well. The same can be said for efficiency, which easily cleared Platinum both times. Even when the unit hit the full fifty degree mark in the hot box. This is a rock solid unit from a performance standpoint， it's easy to find worse units, hard to find better.

The DW1250's most notable advantage, most likely the decisive factor in its purchase, is that it manages to combine high capacity and efficiency with a fairly silent operation at, especially, light- to mid-level loads under normal operational conditions. The DQ1250 managed to survive all of my incredibly tough tests and operated flawlessly even while the ambient inside my hot box reached 47°C over prolonged periods of time, which reveals a lot about its reliability, it managed to perform very well throughout and is probably the quietest high-end PSU I have ever tested.
